The paper describes an ongoing project that pursues the idea of query-driven data integration. Instead of first creating a common global schema and fetching, transforming, and loading the data to be integrated, we start with the queries. They are taken as a specification of information need and thus as the overall purpose of integration. Two repositories are being developed, one for all informa...

The article was, perforce, a brief one in which the main aim was to correct some common misunderstandings about preparation of LFA matrices. I tried to emphasize that the creation of a LogFrame should be ‘preceded by a small group of secondary stakeholders who should base their discussions on a thorough needs assessment (or problem tree)’ and I also emphasized the need for wider stakeholder ana...

The concept of using critical decisions as a basis for defining Information needs has been suggested by several authors. This article reports on results of a decision.oriented approach to planning for MIS. A structured group process Is used to generate both critical decisions and Information needs for a manufacturing firm. Results indicate that the decision approach is effective, particularly f...

Isolation of unknown DNA sequences flanked by known sequences is an important task in molecular biology research. Thermal asymmetric interlaced PCR (TAIL-PCR) is an effective method for this purpose. However the success rate of the original TAIL-PCR needs to be increased, and it is more desirable to obtain target products with larger sizes. Here we present a substantially improved TAIL-PCR proc...

A Data Analysis System for Industrial and Enterprise Greenhouse Gas Emission, for meeting the needs of the giant energy-consuming enterprises has been set up through a series of studies on the verification method of Greenhouse Gas (GHG) in industries such as cement, thermal power, cogeneration, transport, sewage treatment etc. The analysis system consists of six modules: Organization Structure;...

Riboflavin (RF), also known as vitamin B2, belongs to the class of water-soluble vitamins and is widely present in a variety of food products. It is sensitive to light and high temperature, and therefore, needs a consideration of these factors for its stability in food products and pharmaceutical preparations. A number of other factors have also been identified that affect the stability of RF. ...

Subjects with Bell's palsy and healthy individuals were treated with moxibustion thermal stimulation on the Hegu (LI4) acupoint; an infrared thermal imaging system was used to observe facial-temperature changes. Bell's palsy patients developed low or high temperatures at the affected side, with poor symmetry. Healthy people showed high temperatures on the forehead, medial angle of the eye, nasa...

Nanofluids are a new class of fluids engineered by dispersing nanometer-size structures (particles, fibers, tubes, droplets) in base fluids. The very essence of nanofluids research and development is to enhance fluid macroscopic and megascale properties such as thermal conductivity through manipulating microscopic physics (structures, properties and activities). Therefore, the success of nanofl...

2014 The concept of dwelling is connected with the thermal comfort problem. Radiatively out of balance volumes may agree physiologically and psychologically with the ideal preferred comfort. Nevertheless taking into account vertical and horizontal gradients is a necessity, as well as other parameters of influence like air temperature, air velocity, hygrometry, activity and clothing. The mean ra...

Driven by the needs of engineered underground systems, the field of rock mechanics is evolving to address the interactions of in situ mechanical, thermal, hydrologic, and chemical processes and their effects on system performance. Important technical issues include understanding how the relevant loads and gradients drive in situ processes; rock mass variability, discontinuity, and heterogeneity...
